Hemorrhagic transformation of ischemic stroke pdf
Background and purpose Hemorrhagic transformation (HT) is a complication that may cause neurological deterioration in patients with acute ischemic stroke.
Ischemic stroke is a common complication of infective endocarditis (IE), occurring in 20-40% of left side IE cases. In these subsets, anticoagulation therapy may provoke hemorrhagic transformation (HT) of ischemic stroke, and complications of this magnitude deteriorate the clinical course for IE patients. However, in cases of IE complicated with a mechanical prosthetic valve, the physician can

This hemorrhagic transformation occurs because all tissue (brain and vasculature) downstream of an ischemic stroke becomes ischemic. In many cases, blood flow to the ischemic area is reestablished too late to benefit the brain and returns via weakened, damaged vessels. These vessels may leak, resulting in petechial hemorrhage, or burst, resulting in a hematoma. Hemorrhagic transformation is
The rate of hemorrhagic transformation of an ischemic stroke of 59% is much higher than that reported in the stroke thrombolysis literature. As our surviving patients achieved an mRS score of 2-4 and a GOS score of 3-4, the presence of any type of new hemorrhagic transformation in this patient population does not appear to alter the natural history of their ischemic strokes.
Presence of arterial vascular occlusion is commonplace in ischemic stroke patients who have hemorrhagic infarct transformation with or without thrombolysis . Potentially, the likelihood of hemorrhagic conversion was triggered by more severe ischemia in patients with lower CBS as indicated by higher baseline NIHSS scores and lower baseline ASPECTS in our study. Furthermore, higher …

Hemorrhagic transformation (HT), which refers to a spectrum of ischemia-related brain hemorrhage, is a frequent spontaneous complication of ischemic stroke, especially after thrombolytic therapy . Therefore, HT limits the use of tissue plasminogen activator (tPA) treatment, the only method of clinical management of acute ischemic stroke.
The term symptomatic hemorrhage secondary to ischemic stroke implies a clear causal relationship between clinical deterioration and hemorrhagic transformation (HT) regardless of the type of HT. The aim of this study was to assess which type of HT

The rates of hemorrhagic transformation of ischemic strokes have been variably reported, but generally over half of all cerebral infarcts at some stage develop some hemorrhagic component. The majority of hemorrhagic transformation after stroke (89%) is petechial hemorrhages; a minority (11%) hematomas 5,6 .

PDF ABSTRACT. ABSTRACT. Reperfusion therapy contributes to better clinical outcomes in patients with acute ischemic stroke but carries a more significant risk of hemorrhagic transformation (HT) compared to supportive care. Once HT occurs, the outcome is usually poor and this causes a dilemma in the treatment of ischemic stroke. Consequently, early prediction of HT would be extremely helpful

Hemorrhagic transformation (HT) increases the morbidity and mortality of ischemic stroke. Anticoagulation is often indicated in patients with atrial fibrillation, low ejection fraction, or mechanical valves who are hospitalized with acute stroke, but increases the risk of HT.
Some causes of hemorrhagic stroke are hypertensive hemorrhage, ruptured aneurysm, ruptured AV fistula, transformation of prior ischemic infarction, and drug induced bleeding. They result in tissue injury by causing compression of tissue from an expanding hematoma or hematomas.
Hemorrhagic transformation occurs in 20-40% of stroke patients within the first week after symptom onset and is a major complication of thrombolytic therapy for acute ischemic stroke . Microbleeds are strongly associated with intracerebral hemorrhage (ICH) and are considered a marker of bleeding-prone microangiopathy [3, 4].

Conclusions: Hemorrhagic transformation of an ischemic lesion does not affect rehabilitation outcome in stroke survivors. The study results favor the use of anticoagulants and antiaggregants in the acute phase unless these drugs are contraindicated by the patient’s condition. Still, prospective trials are needed to make definite conclusions.
